caliber change

You could change or modify the bolt for a 6BR, BRAI, or Dasher.

Those all use a .473 bolt face and his has a .540 bolt. There are no replacement bolts available for a WSSM action.

Numrich will most likely have a replacement bolt of you want to change. Link below.

Then it would need to be modified.

Then it would need to be modified.

The WSSM uses a .540 bolt face, modifying it to take a smaller diameter case head isn't practical or cost effective.

Seems like all the OP can do is to put the WSSM into the gunsafe and start from scratch with what he wants to do.
